【摘要】：茚三酮是显现渗透性客体上潜在汗液手印的最常用方法之一,采用微量物证提取纸和茚三酮溶液有机结合制作的茚三酮固体介质可以有效避免客体表面背景着色,不容易引起纸张油墨扩散,另外避免使用的溶剂易燃。能够更便捷的显现现场指纹,并且能够突破茚三酮只能显现渗透性客体的局限,拓宽茚三酮显现客体的范围,在热敏纸上潜指纹的显现方面有独特的应用优势。
[Abstract]:Ninhydrin is one of the most commonly used methods to show the latent sweat handprints on the permeable object. The indene trione solid medium which is made by the organic combination of trace physical evidence extraction paper and ninhydrin solution can effectively avoid the background coloration on the surface of the object. Not easy to cause paper ink diffusion, in addition to avoid the use of flammable solvents. It can more conveniently show the field fingerprint, and can break through the limitation of the permeable object of ninhydrin, widen the scope of ninhydrin to show the object, and have a unique application advantage in the display of latent fingerprint on thermistor paper.
